Dance therapy is the use of dance methods, usually under the direction of a therapist, to assist in healthcare.  The most common applications are expressive dance as part of psychotherapy, or dance movements as part of physical and rehabilitation medicine intended to improve agility and movement.
While aerobic dance is a popular form of exercise, which does improve cardiovascular fitness as well as strength and flexibility, that technique is generally considered to be separate from dance therapy.
Umdergraduate preparation is typically in liberal arts containing psychology courses, and extensive dance experience. Entry into the profession is at the master's degree level, "The title "Dance Therapists Registered" (DTR) is granted to entry level dance/movement therapists who have a master's degree which includes 700 hundred hours of supervised clinical internship. The advanced level of registry, "Academy of Dance Therapists", (ADTR) is awarded only after DTRs have completed 3,640 hours of supervised clinical work in an agency, institution or special school, with additional supervision from an ADTR."
